Aryl Hydrazide beyond as Surrogate of Aryl Hydrazine in the Fischer Indolization: The Synthesis of N-Cbz-indoles, N-Cbz-carbazoles, and N,N′-Bis-Cbz-pyrrolo[2,3-f]indoles
摘要:
Aryl hydrazides underwent the Fischer indolization reactions, while the N-carbamate group(s) remained intact to directly provide N-Cbz-indoles. This new method allowed the synthesis of various N-Cbz-carbazoles and N,N'-bis-Cbz-pyrrolo[2,3-f]indoles.

method involving a formalhydrohydrazination/ Fischerindolizationtandemreaction to synthesize 2,3-disubstituted indoles from alkynes and arylhydrazines has been developed. The approach uses a Ph 3 PAuNTf 2 /pTSA·H 2O binary catalytic system in which a very low catalyst loading of Ph 3 PAuNTf 2 (2 mol-%) is required. The reaction time is very short and, most importantly, the reaction is not sensitive

we present a highly efficient enantioselective synthesis of monoheteroaryl N–N atropisomers via an asymmetric Paal–Knorr reaction, affording a diverse array of N–N amide–pyrrole atropisomers with excellent enantioselectivities. Gram-scale synthesis and post-transformations of the product demonstrated the synthesis utility of this method. Racemization experiments confirmed the configurational stability
